Knowledge of plastic packaging bags

1, can be repeatedly melt forming and basic can keep its characteristics of hot shaping plastic. 2, only a molten thermosetting plastic molding. Main properties of plastic: 3, density is small, higher than strength, can get a higher rate of packed. 4, most of the plastic good chemical resistance, long placed, not prone to oxidation. 5, molding easily, the energy consumption is lower than steel molding of metal materials. 6, has the good transparency, easy coloring. 7, has good strength and unit weight of high strength, impact resistance, easy modification. 8, low processing cost. 9, insulation is better.
